So, let me get this straight...

... we should be worried about the U.S.-China climate plan because it may not require China to do enough, and because it may be too ambitious for China to achieve...?

Still, many questions surround China’s plans, which President Xi Jinping announced in Beijing alongside President Obama after months of negotiations. In essence, experts asked, do the pledges go far enough, and how will China achieve them?

Realism and skepticism are warranted, of course. But I can already hear the GOP and carbon lobby talking points. There is a natural progression of arguments from the people who would prefer to do nothing about climate change: from denial of warming, to denial that humans are causing it, to it's happening but it's too costly to do anything about it, to we could do something at reasonable cost but the Chinese won't, so why bother? The next step, logically, is to claim that whatever China agrees to do will fail regardless. Sigh.
